Operation
- Power on/off
Power on: Plug in the power supply, short press the right side button to turn on the instrument.
Power off: Long press the right side button to turn off or press “Power off” in the menu bar. - Calibration
After entering “calibration” interface, you can perform calibration operation as the calibration animation, or skip the calibration. It is recommended to calibrate after a long time of no usage.
For failed calibration, the possible reasons are as below:
◆ The dust cover has not been removed or the test holes are covered with samples;
◆ Tested in a bright light environment;
◆ The attenuation of the light source leads to failure of normal use and it needs to be returned to the factory for inspection and repair. - Measurement
The default measurement parameter of the instrument is “Haze/Transmittance”. Users can click the “Param” at the top of the screen or the “Param Setting” in menu bar to enter the setting interface to select the parameters to be measured (H/T, H, T, CIE_Lab, CIE_LCh, Yxy, Spectra, Clarity,Turbidity,PtCo).
Entering the measurement interface, you can click the ” Compare” on the top of the screen to switch the compare measurement mode.
3.1 Compare off
In the measurement interface, click on “Scan” or short press the button on the right side of the instrument to measure.
The following steps can be performed after completing measurement:
⚫ Save
To save the comparison result, press “Save” on the upper right corner. You can choose default or name the record manually.
⚫ History
If users need to view the saved results, click “History” to view the records, and records can be paged, deleted, renamed and searched.
3.2 Compare on 
In the measurement interface, press the “Scan Standard” button to set current value as standard. Press the “Scan Sample” button to use current value as sample. If short press the button on the right side, another measurement will also be taken and the current value will replace the previous one. When measuring or adding a standard and measuring a sample, the difference or color difference between the two measured values will be calculated with the following results:
◆ The difference value
The difference Δ is the sample data minus the standard data;
◆ Color Bias
When the measurement parameter is selected as Lab, the color bias will be judged by ΔL, Δa, and Δb;
◆ Δ E value
When the measurement parameter is selected as Lab, LCh, or Yxy, ΔE is calculated using the ΔE*ab color difference formula;
◆ QC test
Suitable for difference inspection in production process. If ΔE is higher than the set threshold, it will read “NG” and sown in red; if ΔE is less than or equal to the set threshold, it will read “Pass” and display in green.
The following steps can be performed after completing compare measurement:
- Save
To save the comparison result, press “Save” on the upper right corner. You can choose default or name the record manually. - History
If users need to view the saved results, click “History” to view the records, and records can be paged, deleted, renamed and searched. - Save standard
After the user has finished measuring the standard value, if need to save it for later calling, click the ” Save standard” to save it, and the saved value can be queried in the add standard interface. - Add standard
After clicking “Add standard”, the interface will jump to “Add standard”, click the value you want to add, and the selected value will be used as the standard, and will automatically return to the measurement interface to compare with the current sample or the upcoming sample. - Input standard
The user can manually input the Haze, Transmittance, Lab, LCh, Yxy value as standard. - Tolerance Setting
Setting the threshold for QC inspection.
In the measurement interface, click the “

V PC Software
You can use the PC software to connect the computer via USB. The software has functions of compare measurement, reading compare record, export compare data to Excel, qualified number, unqualified number, total number statistics, report generation and printing, etc. For specific operation, please refer to the “Color Haze Meter Software Operation Manual”.
Precaution
- When the colorimeter has not been used for a long time, it is recommended to perform calibration before using.
- Please ensure that the sample is evenly colored with a flat and clean surface, otherwise it will affect the measurement accuracy.
- Avoid liquids entering the instrument through the measurement aperture, as this will damage the instrument and affect measurement accuracy and operational safety.
- When the instrument is not in use, put on the dust cover to prevent dust from entering or prolonged humidity, which may affect the measurement accuracy.
- It’s recommended to calibrate the instrument once each year. And we offer calibration service.
- Due to color difference in the LCD display, the color displayed on the instrument screen is for reference only.
- When measuring the haze, transmittance, color, clarity, turbidity, pt-co, in order to measure more accurately, it is necessary to fill pure water into the cuvette to calibrate it before measurement; at the end of the measurement, it is necessary to remove the test object to recalibrate again.
- Modify the standard settings (standard, measurement aperture, measurement conditions) parameters of the instrument, need to recalibrate.
